SELF-SUPPORTING CARRIAGE BODY FOR MOTOR-DRIVEN VEHICLES.

Application filed Iuly 22, 1925, Serial No. 45,322,

This invention relates to a self-supporting carriage body for motordriven vehicles and it consists in that the carriage body is cast in onepiece with the frame, the engine bon- 55 net, the case for the steeringgear, the benzine and oil reservoirs, and the transverse andlongitudinal stifienings. A portion of the longitudinal stifiening whichis constructed, in known manner, to journal the driving shaft, extendsin upward direction so that it serves at the same time as arm supportsfor the occupants of the car. The invention consists further in that inthe engine bonnet dove-tail shaped guide ribs are arranged on which theengine and the radiator are fixed so that they can be easily exchanged.

The carriage body is specially distinguished by simple and cheap,manufacturing and further by light weight as aluminium can be used ascasting metal. Bend ng or edging within the sheet metal plates andchannel-iron bearer is absolutely prevented which happens frequently inthe commonly used carriage frames.

The spring suspension is mounted on axles which traverse the carriagebody in order to distribute over the entire load the shocks produced bythe unevenness of the road and to soften the same as much as possible.

An embodiment of the invention is shown, by way of example on theaccompanying drawing in which Fig. l is a longitudinal section of theimproved body and frame.

Fig. 2 is a horizontal section of the same.

Fig. 3 is a vertical cross section through the front portion of thecarriage body.

Fig. 4; is a vertical cross sect-ion of the body and frame.

As Figs. 1 and a show clearly, the carriage body a and the frame arecast in one piece, preferably from aluminium which presents theadvantage to be of lighter weight and cheaper in manufacturing thanother material. The bottom 5 is either entirely or partly double-walled,the upper wall of the bottom having the shape ofseats to be fitted withcushions.

Ribs c and partition walls at on the bottom and on the side walls serveto stifi'en the carriage body and to increase the stability. Thepartitions d are shaped to serve as seat backs and arm supports.

In order to obtain a mounting of the drivmg shaft free from shocks thebottom a has a U-shaped upwardly directed projection f which extendsalong the central line of the bottom.

As shown in Figs. 2 and 4 this hollow rojectlon f divides the seats intotwo ha Ves forming at the same time the middle arm support.

Underneath the rear seats a box-shaped hollow compartment 9' is arrangedwhich extends transversely across the carriage frame and serves toaccommodate the rear axle it. By this shape of the bottom of thecarriage suficient play in vertical direction is given to the drivingshaft and to the rear axle, so that, when strong shocks occur, thespring suspensions of the axles are sufficiently equalized. The axlesprings for the rear axle are attached at i and z".

The seats are arranged in an especially practical manner as they aresituated very 75 deep and have high backs so that the weight is as fardown as possible, any danger of skidding and turning over bemg avoided.The car opposes a smaller surface to the wind as it is much lower owingto the arrangement that the seats are arranged at the sides of theCardan shaft instead of above the same.

The front portion of the carriage body, in front of the drivers seat,forms the engine bonnet on which the casing m of the steering gear iscast, the roof of the engine bonnet forming the benzine reservoir It andthe oil reservoir Z. n is the steering wheel. The engine is guided,together with the radiator 0, upon dove-tail shaped guides p, Fig. 3, sothat the engine can be easily removed together with the radiator and putin again. The front portion of the carriage body and of the guide ribsmay be of any convenient shape.

Underneath the engine bonnet supportin springs for the front wheel axleg are fixe at either side, the arrangement being such that the frontaxle is situated together with the front or steering wheels in front ofthe radiator whereby the steering of the car is facilitated. The enginebonnet has apertures t in its sides, which are adapted to be closed .byany convenient means and facilitate the access to the engine. In theside walls of the carriage body doors are arranged as usual.

For technical reasons the carria 0 body mi ht he cast in two longitudinahalves WhlCh have to be united. I

The improved earria e body can be cast 1n any size together wit theaccessories, as mud guards u, benzine tanks, fixatlon for spare tiresand the like.

' I claim 1. Self-supporting carriage body for motor driven vehicleseast in one piece with the frame, the engine bonnet, the benzinereservoir, the oil reservoir, the casing for the steerin gear, and thecross and'longitudinal sti enings.

2. Self-supporting carriage body for motor driven vehicles cast in twohalves but in one piece with the frame, the engine bonnet, the benzinereservoir, the oil reservoir, the oasin for the steering gear and thecross and longitudinal stifienings.

3. Se f-supporting carriage body for motor driven vehicles cast in onepiece with the frame, the engine bonnet, the benzine reservoir, the oilreservoir, the casing for the steer-in gear and the cross andlongitudinal sti enings, a portion of the longitudinal stifiening beingraised so that it forms a hollow web designed to accommodate the drivinports for t e seats.

4. Self-supporting carriage body for motor driven vehicles cast in onepiece with the frame, the engine bonnet, the benzine reservoir, the oilreservoir, the casing for the steering gear and the cross andlongitudinal stiffenings, dove-tail shaped guide ribs being arranged onthe inner surface of the side walls of the engine bonnet to serve asguides for the engine and the radiator to facilitate the removal andinsertion of the same.

In testimony whereof I aflix my signature.
